Meiyu season, field work of vegetables and watermelon

Tomatoes are recommended to choose infinitely growing varieties, and it is not advisable to choose self-sealing top varieties. Tomato varieties can choose: cooperation 908, Zhongza 9th, red powder champion, Hefen 902, the above varieties are suitable for summer and autumn planting, high temperature resistance, good quality, high yield and resistance to transportation. If you plant autumn tomato, choose a short growing period, seedlings at the end of July and early August, planting in September, seedling age 28-32 days, such as: Zhejiang powder 702, powder 802, red powder 402.

Cucumber varieties suitable for summer and autumn planting: It is recommended to choose varieties with long growth period and disease resistance, such as: Jingyou No. 1, Zhongnong No. 8, and Qiushu No. 1. The above varieties have small leaves, long growth period, high yield, and can be covered with each other. Yin, acre planted about 4,000.

The varieties of autumn peppers can be selected: Zhengjiao 18, Qijiao No. 4, and Sujiao No. 5 Dr. Wang.

Nursery preparation

It is recommended to seedling seedlings, seedlings are not recommended, because seedlings should be divided into seedlings, the risk of seedlings is large, and the survival rate of hot roots is low. The seeds are soaked for about 6 hours before planting, and they are fed into nutrient bowls or burrows. Watering the water, then masking the seeds (make sure to cover the seeds and cover the seeds, if exposed, it will lead to no emergence), then build two layers of shade nets, one layer on the seedling shed, one layer on the overhead small arch shed, emergence Afterwards, the sunshade net of the next layer should be removed in time. The upper layer of the sunshade net is recommended to be covered at noon at high temperature, and it will be removed sooner or later.

Mr. Feidong Wei Consultation: During the flowering period of the melon, the white mold was found at the bottom of the root, and the leaves were black with curls.

Teacher Zheng replied: Initially judged as a disease or leaf blight, it is recommended to use 33% quinoline copper or 20% leaf cumin. The white mold at the bottom of the root may be the pre-symptom of root rot. It is recommended to use 95% carbendazim or 50% iprodione or 75% dikesone.

Mr. Shu Cheng Xue Consultation: This year's watermelon is a long fruit type. When mature, the lower outer skin has 10% yellow, yellow and red color, which affects the selling phase. What is the reason?

Teacher Zheng replied: Oval watermelon is prone to sunburn at high temperatures, mainly due to the fact that the melon is thinned when the whole branch is made, causing the watermelon to be exposed. It is caused by sunlight. It is recommended to pull the melon to prevent sun exposure and add chlorine. Calcium or superphosphate.

Mr. Fei Xi Li Consultation: There are many dead cockroaches in the greenhouse, and the root rot is caused by the rot, but the autumn pepper can not be changed. What should I do?

Teacher Zheng replied: Long-term continuous cropping of pepper easily leads to root rot and bacterial wilt, and it is impossible to prevent it. If it is necessary to continue to work, be sure to sterilize the soil with a high temperature shack. The method is: clean the dead leaves and peppers before entering the volts, sprinkle with 100 kg - 200 kg of ammonium bicarbonate - plowing down - spray water - cover the film, gland tight - high temperature shack; or spray first Wet soil - sprinkle with lime eggs 200 pounds - immediately plowed - conditionally covered with film.

Mr. Feixi Tang Consultation: The melons of the two melons are like pig blood, why?

Teacher Zheng replied: This is a water-immersed melon, 6-7 mature shed on the side of the water, or caused by excessive watering. Watermelon should not be flooded with large water. If it is too dry, it should be watered in the evening. It is recommended to drip for 10 minutes every 3 days.

Ms. Fei Xi Li Consultation: There is a piece of cognac when the open field pepper is ripe. What happened?

Teacher Zheng replied: This is a thin and thin seedling with a small leaf area and chlorophyll can not keep up. It is recommended to add calcium or spray foliar fertilizer. Calcium supplementation with calcium chloride, or after soaking the superphosphate, take the soaked liquid to spray.

Extraction Kit Magnetics Bead Method

This standard specifies the terms and definitions, classification, technical requirements, test methods, identification, labels and instructions for use, packaging, transportation and storage of nucleic acid extraction kits (magnetic beads method) (hereinafter referred to as "kits"). This standard It is suitable for extracting and purifying human genomic nucleic acid and its fragments from various clinical samples such as serum, plasma, whole blood, cerebrospinal fluid, milk, saliva, urine, sputum, swab, tissue or paraffin-embedded tissue by magnetic bead method , Pathogen nucleic acid kit. Pathogen nucleic acid includes deoxyribonucleic acid (DNA), ribonucleic acid (RNA), etc. This standard does not apply to nucleic acid extraction reagents contained in closed systems that cannot extract nucleic acid extraction products for detection.

This kit uses magnetic beads with unique separation function and a unique buffer system to separate and purify high-quality virus from serum, plasma, lymph, cell-free body fluid, cell culture supernatant, urine or various virus preservation solutions DNA/RNA. The uniquely embedded magnetic beads have a strong affinity for nucleic acids under certain conditions, and when the conditions change, the magnetic beads release the adsorbed nucleic acids, which can achieve the purpose of rapid separation and purification of nucleic acids. The whole process is safe and convenient, and the extracted viral DNA/RNA has high yield, high purity, stable and reliable quality, and is especially suitable for automated extraction of high-throughput workstations. The nucleic acid purified by this kit can be applied to various routine operations, including RT-PCR, fluorescence quantitative PCR and other downstream experiments.
